We have a number of innovative Ground Floor solutions that can be used in either new-build or renovations.

These include the FastSlab ground floor for replacing rotten suspended timber floors with an insulated, light weight screeded ground floor often incorporating underfloor heating, the FastSlab foundation system that includes steel screw-piles and an insulated ring-beam system for light weight new build houses.

We also have the insulated Op-Deck system for high loads, large spans and cantilevers that includes an optimised concrete T-beam floor design.

Ground floor solutions are always worth discussing to ensure that they fit with the project and the conditions of the proposed site or design.

This should be done as soon as possible within the detailed design phase of the project to give the best chance of success. We are always happy to provide our guidance as to whether our systems are suitable or not and if they add to the project.

    What are the Lewis Deck sheet sizes?

    A

    Q: What sheet sizes are held in stock for delivery within a few days after order?A: We stock 2500mm and 1300mm sheets.  These are all 630mm wide and 16mm deep.  Deliveries are made via the pallet network directly to site.  The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT.2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*.

    Q

    Lacomet – How come it has no scrap value?

    A

    Lacomet – How come it has no scrap value?Many of the projects that we get involved in starts with a phone call or email to us from someone researching replacing stolen leadwork. Many of these are old buildings, such as schools or churches, where this isn’t the first time that the lead has been stolen and they call us fed up with having to replace it again full in the knowledge that they will more than likely go through the same problem once more in the near future if they continue to use lead.One of the big benefits that Lacomet FL brings to a project is the fact that it has no scrap value and therefore the chances of it being stolen are massively reduced.Due to the 2 thin aluminium layers, and its five layer total construction, it is of no value to thieves. Lacomet can be recycled but the polyester based coating would need to be de-laminated first and the amount of recovered aluminum is then very low, in fact it would be easier and more profitable to collect empty drinks cans than to mess about stripping Lacomet down. We can also supply stickers that can be placed in strategic locations informing people that what is now on the roof is not lead and that it has no scrap value.

  • Q

    Why don't my Lewis sheets interlock like they do in the video?

    A

    Q: Why don't my sheets interlock like they do in the video?A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.

    Q

    Is this a question?

    If it is, this is an answer.
